' oIL-BURNE To all whom it may concerni Beit known that I, W ILLIAM F.'HOGAN, a

. citizen of the United States, residing in the perspective view of themixer. In an apparatus for burnng crude mineral oil t s customary tomject steam or air city and `county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Oil-Burncrs, ofwhich the following is a specification.

y nventon relates to mprovements in burners for hydrocarbon oils. Itconsists' in the combination' of mechansm and in details ofconstruction, which will be more fully explained by reference to theaccompanyng drawings, in' which- Figure 1 is a longitudinal verticalsection of the apparatus Fig. 2 is a' 'transverse sec-1 tion takenthrough X X of Fig. 1.' Fig. 3 is a must be taken apart and cleaned.

It is the object of my invention to provide 4 an atomizer and mixer ofsuch character that 30 'no clogging of the passages will' take place.

As shown in the drawings, A is an outer steam-tube, and B is an inneroil-tube. These 'tubes are connected b a suitably-constructed coupling,as at C,- aving separate chambers, into `one of which, D, steam isadmitted .under pressure, and into the other one, E, oil

is admitted, and 'from these ehambers the a steam and oil areres'pectively transmitted through the pi es A and B.

2 is a plug o metal, the body of which i cy-- lindrieal, and the endinto which the pi e B is screwed has a :chamber 3 of'sufficient iameterand 'screw-threaded to receive the corres ondirigly-threaded end of thepipe B; The diameter of the cylindrical portion of the plug 2 issufficiently less than the interior di- V ameter of the pi e A so thatthere will be an gannular channe formed between the two.

asshown, the angle's of the recta le eing slightly cut away and fittingsnu y in the pipe A. I The urfaces' of this hea between the angles thusform chords to subtend the "arcs of theinterior of the tube A, thusroviding segmental passa es 4 through w ich' steam from the annular cannel between the" Patented .Tune 19. 1906.

channel 'surrounding the part 2. 4 This part 2 has an annula'r grooveturned around it, as shown at 5, the groove being about three-sixteenthsof an inch in width. From the chamber 3, into which the pipe B 'isscrewed, a three-sixteenths-inch hole 7 is bored into the reduced shank6, which is formed by turning the groove 5, and a three-sixteenths-inchhole 8 is made radially through one side of the pipes A and may passinto the annular reduced shank 6 and connecting with the hole I Thus anopening of suflicient diameter to prevent cloggngis made for thedelivery of the oil from the pipe B into the annular chamber between theplug 2 and the interiorof the pipe A.

Where the oil and the steam meet the jets e of Steam traveling parallelwith the aXes of the parts impel the oil directly against the shoulder9, which is formed in a coupling 10, into which the pipe A is screwed;The coupling is reduced so as to receivea three-eighthsinch pipe 11, towhich the end of the burnertube 12 is screwed. The shoulder 9 is thusformed by the reduction of-the coupling' 10, and the oil being forciblydriven against this shoulder by the jet of steam is finely atom izedbefore passing out through'the connecting-tube 11 into the burner-lead12.

The burner-head 12 is here shown in the form of an' elbow having anupwardly-turned portion, and in the front of this upwardlyturned portion'is made a' horizontal' segmental slot 13, through which the combustiblevapor is' discharged. The upper end of the u turned portion of theburner-head 12 is c osed by 'a screw-plug, as at 14, thus providing aneasy access to the interior, ii' required. I have `found that by the useof the ?plug 2, with the groove and the open passage 7 and -8, throughwhich the oil passes, the` e will IOO Having thus described my'mvention,what v An improvedpil-burner having in combi- I claim, and desire tosecure by Letters Pat- "ent is- The headA-of the part 2 ismade rectanular, J
